The fact that the rescaling in the settings gave different results from
what we got after a restart really should have been a dead giveaway that
the code was fundamentally flawed.
With this, if the user picks smaller, regular, or larger they now always
get the same, consistent values for gridUnit and font sizes.
This also gives up on the idea that we can just force the gridUnit to be
smaller to make things work if the font (which drives the gridUnit) is
too big for a screen. That fundamentally cannot work and gives a
horrible UI experience. So instead simply warn the user and continue
with matching font / gridUnit, which will still give a bad experience,
but at least we told the user about it and didn't pretend this was ok or
fixable.
Finally, this gets the factors right when switching from smaller to
larger or back, without stopping at regular on the way.
One odd side effect of this code is that under certain conditions
(number of columns changes) the display window when running mobile on
desktop will resize. That's kind of odd, but as that is not /really/ our
target platform, for now I'd consider it acceptable. But it does deserve
more investigation.

Android appears to set its default font in pixels, not points. So guess
the point size based on the font metric information. This is not
perfect, but creates results that are good enough.

We need to do this before the preferences are loaded, or the system
default size is lost. Given that our other sizes are all relative to
this value, that would be a problem.
With this we can now ensure that we always have the right font size for
smaller, regular, and larger theme settings.
Also removes some obsolete commented out code.

As it turns out, we used to get the font scaling completely wrong. As a
result we got got ~72% and ~132% instead of the intended 85% and 115%.
So now people have both options, in each case with matching gridUnit
(and therefore visual spacing), and font size.
Also visualize the font size by rendering the button text accordingly.

The mobile scale code had a fundamental flaw: we applied the scale
factor once to gridUnit, but twice to the font size. So effectively we
had font sizes of 72% and 132% (all of course then rounded to integers
for no good reason) instead of the intended 85% and 115%.

The goodness of fit of a regression line is the percentage
of the variance of the y values that is explained by the
dependence on the x values.
Set the alpha value of the regression line to this goodness
of fit.
Further, set the width of the regression line to a standard
deviation of the values from the regression line valies.

There are two sets of messages that tend to dominate the logs
- the RSSI updates from the Qt BLE stack
- the warnings about deprecated signal use in Kirigami
Neither of them provide any value to us when trying to find bugs; and
often they end up hiding the things that we really care about. So let's
just not log them - which is easy as we have our own message handler.

When setting a CCR setpoint, the profile code(!) would turn
the dive into a CCR dive. Not only should the display layer
not alter dives, this also means that the action is not
undoable.
Move that to the appropriate undo command, where it makes
more sense, but obviously also makes things more complicated.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
The make_first_dc() function clones a dive with a certain dive
computer moved to the front. This is used by the
MoveDiveComputerToFront undo command.
make_first_dc() calls invalidate_dive(). However, the undo
command does that by itself on every undo/redo. Thus,
remove the call in make_first_dc().
Aside from consistency, the goal is to move invalidate_dive()
to command/* so that we can be more aggressive about the whole
topic: Store only "const dive *" pointers and thus force any
writing access to explicitly invalidate the dive cache.

In categorical axes all labels were printed leading to a big

Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
The old code didn't consider that labels can peak out of
horizontal axes if labels are under ticks.
This commit takes this into account. However, it must be
noted that this is only heuristics: Before setting the
size of the axes, the actual minimum and maximum label are
not known, because we round to "nice" numbers. But the
size of the axis can only be set after knowing the overhang,
leading to a circular dependency. Therefore, the code
currently simply uses the minimum and maximum value of
the data, hoping that the "nice" values will not format
to something significantly larger. We could do a multi-pass
scheme, but let's not for now.

The profile had a static variable which prevented animation

Remove this in a step to make the profile reentrant.
The code was quite ominous: instead of simply generating the
list of cylinders, a global model was reset and then accessed
with Qt's cumbersome model/view API. All this trampling over

The profile item that shows the ceilings adds a warning event
if the ceiling is violated. This is very unfortunate.
Improve this situation by adding the event up to the function
that calculates the ceiling. This is still not how it should
be - the display layer should not modify the dive that it
displays.
To make this clear, add a comment that details that this
is a contract between planner and display layer: The planner
uses a dive that can be trampled upon by the profile.
Still, this should be solved differently.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
The in_planner() function is incompatible with a reentrant
profile, since it accesses a global variable. In
create_plot_info_new() it is essentially redundant, because
there is a planner_ds (ds = deco_state) parameter that
is used only when in the planner. Therefore use that as
the in_planner indicator: when non-null, the profile is
showing a planned dive.
